Specifically, the areas of the supporting bodies in the display module are different, and the annular supporting bodies are arranged in the order of the areas from large to small and are spaced at fixed angles. For example, when the supporting member is annular, the plurality of supporting members are arranged in order of increasing radius.
In the present embodiment, the plurality of carriers are coaxially fixed on the rotating shaft 102, and the geometric centers of the plurality of carriers are located at the same point. For example, the carrier is a circular ring, and the centers of a plurality of circular rings are at the same point, i.e. concentric circular rings. Fig. 2 is a top view of a display module with a circular supporting body, and "1", "2" and "3" in fig. 2 respectively indicate an included angle between adjacent supporting bodies.
It should be noted that, the arrangement of the plurality of carriers in the display module may also be adaptively adjusted in practical application, that is, the carriers may not be arranged in the order of the areas from large to small, and the arrangement of the carriers may be set in combination with a specific application scenario.
Specifically, one display unit comprises a first Light Emitting Diode (LED), a second LED, a third LED and a fourth LED which are arranged at the same position of the same supporting body, wherein the light emitting surface of the first LED faces the geometric center of the supporting body, the light emitting surface of the second LED faces away from the geometric center of the supporting body, the light emitting surface of the third LED faces one vertical direction of the plane of the supporting body, and the light emitting surface of the fourth LED faces the other vertical direction of the plane of the supporting body.

The above embodiments are merely illustrative of the arrangement of the LEDs, and do not specifically limit the structure of the display unit in the display module of the present application.
In this embodiment, the annular supporting bodies are arranged in the order of the areas from large to small and at intervals of a fixed angle, so that after the supporting bodies are controlled to drive the display unit to rotate, the omnidirectional display can be realized, and the display effect is good. Meanwhile, during display, the outer layer to the inner layer of the display image correspond to the area of the bearing body in the descending order, and the visible bearing bodies are arranged according to the mode, so that the processing module can conveniently determine the corresponding bright and dark state of each display unit at each moment according to the image to be displayed.
A third embodiment of the present application is directed to a holographic display system, as shown in fig. 3, comprising a processing module 301, a motion driving module 302, a positioning module 303, a display driving module 304, and a display module 305.
It should be noted that the structure of the display module 305 in this embodiment is the same as the structure of the display module 305 in the first or second embodiment, and therefore, the technical details in the first or second embodiment are still valid in this embodiment, and the similar parts to the display module 305 in the first or second embodiment are not repeated.
It should be noted that, in this embodiment, the supporting portion 11 of the display module 305 includes, in addition to the rotating shaft 102, a supporting base 101, as shown in fig. 1, the supporting base 101 is used for fixing the rotating shaft 102; wherein, the processing module 301, the motion driving module 302 and the display driving module 304 are respectively disposed in the supporting base 101.
Specifically, the motion driving module 302 is used for driving the supporting portion to drive the plurality of carriers to rotate under the control of the processing module 301; the positioning module 303 is configured to detect a position of a designated carrier among the plurality of carriers during rotation of the supporting portion under the control of the processing module 301, and transmit the detection time and the position of the designated carrier to the processing module 301; the processing module 301 is configured to predict a position of each carrier at each time according to the detection time and the position of the designated carrier, convert image data to be displayed according to distribution of the plurality of display units, and drive bright and dark display of each display unit through the display driving module 304 according to the position of each carrier at each time and the converted image data.
In the holographic display system provided in this embodiment, the display module 305 is composed of a plurality of supporting bodies, each supporting body has the same shape, the supporting bodies are arranged in the order of the areas from large to small and are spaced at fixed angles, the processing module 305 controls the supporting bodies to rotate at a constant speed, when each supporting body rotates to a different position, the brightness of the display unit on the display module 305 is controlled, and a holographic image is displayed by using the persistence of vision effect of human eyes.
Specifically, the positioning module 303 includes a positioning signal transmitting submodule 401 disposed on a designated carrier, and a positioning signal receiving submodule 402 disposed on an outer surface of the supporting base, as shown in fig. 4, for example, the designated carrier is an outermost ring carrier.
The positioning signal transmitting submodule 401 is configured to transmit a positioning signal under the control of the processing module 301, and a transmitting direction of the positioning signal is directed to the supporting base 101; the positioning signal receiving submodule 402 is configured to detect a positioning signal transmitted by the positioning signal transmitting submodule 401 when the positioning signal transmitting submodule 401 rotates to a position right above the positioning signal receiving submodule 402, and immediately transmit a position of the designated carrier to the processing module 301.
The processing module 301 obtains the position of the designated carrier transmitted by the positioning module 303 at the detection time, where the position is the position corresponding to the positioning signal transmitting submodule 401. Further, the display module 305 includes a plurality of ring-shaped carriers, and the positioning signal transmitting sub-module 401 is located on a designated carrier, for example, the positioning signal transmitting sub-module 401 is selectively disposed on the carrier with the largest ring-shaped area. Under the condition that the bearing bodies move at a constant speed, the processing module predicts the position of each bearing body at each moment according to the relative position relation among the bearing bodies, the movement speed of the bearing bodies and the position of the appointed bearing body at the detection moment.
In one specific implementation, the position information of each carrier at various times is calculated from the time when the positioning signal transmitting submodule 401 passes the position of the positioning signal receiving submodule 402 when the carriers rotate at a constant rotation speed. For example, the carrier provided with the positioning signal transmitting submodule 401 may obtain the position of the carrier at the time corresponding to the rotation time according to the rotation speed of the carrier multiplied by the rotation time. The positions of other carriers at the same time can be deduced according to the position relation among the carriers.
It should be noted that the display principle of this embodiment is that the processing module 301 converts the image to be displayed, determines the coordinate point to be lit in the holographic image in the three-dimensional space, and lights the display unit when the display unit rotates to the coordinate point to be lit during the rotation of the carrier.
The specific method for establishing the spatial coordinates may be: a space rectangular coordinate system is established by taking the geometric center point of the appointed bearing body as an origin, taking the direction vertical to the bearing body with the largest area as an X axis, taking the direction vertical to the X axis and the rotating shaft 102 on the bearing body with the largest area as a Y axis, and taking the direction along the rotating shaft 102 as a Z axis. The space rectangular coordinate system is established for the convenience of the processing module to determine the space position of the display unit to be lighted, and in practice, the space rectangular coordinate system can also be established according to other reference positions, so that the processing module can determine the position information of the display unit to be lighted according to the coordinate system.
In one specific implementation, the positioning signal transmitting sub-module 401 is specifically configured to transmit the positioning signal according to a preset period under the control of the processing module. The transmission according to the period can avoid the power consumption waste caused by the real-time transmission, and the processing module can correct the position of the appointed bearing body at each moment according to the period so as to ensure the display effect.
In one specific implementation, the display process of the holographic display system is as follows: establishing a space coordinate system; the processing module 301 obtains image data to be displayed, converts the image data into display information, and determines pixel points needing brightness or darkness in the spatial coordinate system according to the display information; the multiple carrying bodies are driven by the rotating shaft 102 to rotate, the positioning module 303 obtains the position of the designated carrying body at the detection time, and the processing module 301 can determine the position information of each carrying body according to the position relationship of the multiple carrying bodies; when the bearing body rotates, the display unit moves to a pixel point needing brightness or darkness, and the brightness of the display unit at the corresponding position is controlled according to the display information, so that the holographic image corresponding to the image to be displayed is displayed.
It should be noted that, in the above embodiment, the display unit is lighted at different positions in the three-dimensional space coordinate, so that the image displayed by the holographic display system has a real depth of field, that is, the image of the object to be displayed at different positions and different distances can be clearly displayed, and a user can see the same three-dimensional image as the real object in a range of 360 degrees of the image, thereby implementing holographic display of the image to be displayed.
In a specific implementation, the positioning signal transmitting submodule 401 may be an infrared transmitting module, and then the transmitting module needs to be installed on the outermost carrier, and an infrared receiving device is arranged on the supporting base, and when the carrier passes through the position of the infrared receiving device in the rotating process, then the processing module 301 may learn the position information of the outermost carrier. It should be noted that, the spacing angle between each carrier is fixed, and the infrared emission module may also be disposed on other carriers when the spacing angle is not zero.
It should be noted that, in order to obtain the position information of the carrier during the rotation process, other positioning manners may also be used to obtain the position information, for example, the positioning signal transmitting sub-module 401 is configured as a tracker to position the position information of the specified carrier in real time. That is, the type and positioning manner of the positioning signal transmitting submodule 401 are not particularly limited in this embodiment.
It should be noted that all modules referred to in the embodiments of the present application are logic modules, and in practical applications, a logic unit may be one physical unit, may also be a part of one physical unit, and may also be implemented by a combination of multiple physical units. In addition, in order to highlight the innovative part of the present application, a unit that is not so closely related to solving the technical problem proposed by the present application is not introduced in the present embodiment, but this does not indicate that there is no other unit in the present embodiment.

Meanwhile, people can directly see the displayed image when watching, and the display effect is good.
A fourth embodiment of the present application relates to a holographic display system, and the fourth embodiment is a further improvement on the third embodiment, and the main improvement is that the holographic display system provided in the fourth embodiment further comprises a data input module connected with the processing module; as shown in fig. 5, the data input module 501 is used to transmit the input image data to be displayed to the processing module.
It should be noted that the data input module 501 is disposed on the supporting base, where an input interface of the data input module 501 may be a wireless interface or a universal serial bus interface, which is only an example, and the data input module 501 provided in this embodiment is mainly used to facilitate data transmission, and is not limited to a specific implementation form thereof.
In a specific implementation, the image to be displayed is input through the data input module 501, and is converted by the processing module, if the image is large or complex and the data processing in the conversion process is large, the step of data conversion can be put in the cloud, the data conversion is performed by the remote server, and the converted data result is sent to the holographic display system through the data input module.
In one specific implementation, to ensure the display effect, the processing module 301 is specifically configured to: if the states corresponding to the first time of the third LEDs of the at least two display units on the same horizontal plane are determined to be both lighted according to the position of each bearing body at each time and the converted image data, selecting the display unit on the non-outermost bearing body from the at least two display units, and setting the state corresponding to the first time of the third LED of the selected display unit as a non-lighted state; and/or if the corresponding states of the fourth LEDs of the at least two display units on the same horizontal plane at the first moment are determined to be both lighted according to the position of each bearing body at each moment and the converted image data, selecting the display unit on the non-outermost bearing body from the at least two display units, and setting the corresponding state of the fourth LED of the selected display unit at the first moment as a non-lighted state.
In a specific implementation, collision processing is required before lighting the LEDs of the display unit, taking an example that one display unit includes four LEDs, if a certain display unit needs to be lit, the display mode is as follows: if the display unit needs to be lightened, lightening a first LED and a second LED of the display unit; judging whether a display unit needing to be lightened exists in the light emitting direction of a third LED or a fourth LED on the same plane of the display unit; and if so, setting the state of the third LED or the fourth LED of the display unit to be in a non-lighting state. Because the first LED and the second LED of each display unit do not have display conflict, conflict processing is not needed.
For example, as shown in fig. 6, two circles in fig. 6 are different moving tracks of the carriers, and assuming that there are a display unit a and a display unit B, the display unit B and the third LED and the fourth LED of the display unit a are on the same horizontal plane, if there is a viewer in the lighting direction of the display unit B and the display unit a, that is, the position shown by C in the figure, if the display unit B and the LED that the display unit a needs to be lit are not subjected to the conflict processing, but are all lit, the displayed images in the direction will be overlapped. Therefore, the collision processing can avoid the phenomenon and ensure the display effect of the holographic image in all directions.
